Technical Field

[0001] This utility model relates to a concealed zipper three-in-one machine, and more specifically to a zipper pull device for a concealed zipper three-in-one machine. Background Technology

[0002] A zipper consists of two zipper straps, a slider, and corresponding teeth on the zipper straps. Depending on the application, the top and bottom ends of the zipper straps can be equipped with top and bottom stops. Zippers are also classified by material, including metal zippers, nylon zippers, and resin zippers.

[0003] In related technologies, the production process of nylon zippers includes cutting, threading, and stopping. However, in existing equipment, each process is basically carried out separately by different machines, which is cumbersome and has low production efficiency.

[0004] Therefore, the existing technology includes an invention patent with publication number CN110623378B entitled "Nylon Zipper Three-in-One Machine," which discloses a feeding device, cutting device, tape transfer device, threading device, melting and stopping device, and discharging device to realize the feeding, tape transfer, threading, melting and stopping, and discharging operations of zipper tape. However, this invention patent performs the melting and stopping operation directly after threading. In contrast, invisible zippers require the zipper tape to be stacked and flipped after threading before the melting and stopping operation is performed to achieve the invisible effect. The aforementioned existing technology, on the other hand, directly performs the melting and stopping operation. Therefore, it is evident that the aforementioned nylon zipper three-in-one machine is not suitable for the production of nylon invisible zippers. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a zipper threading device for a three-in-one machine for processing nylon invisible zippers that is well applicable to the processing of nylon invisible zippers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a zipper pull device for a three-in-one invisible zipper machine, comprising a pull device and a mounting and flipping device. After the zipper tape passes through the pull device, it is fed into the mounting and flipping device for tooth flipping. The mounting and flipping device comprises an upper flipping mold and a lower flipping mold. The lower end of the upper flipping mold has an upper flipping groove, and the upper end of the lower flipping mold has a lower flipping groove. The upper flipping groove and the lower flipping groove are arranged opposite to each other to form a flipping channel that drives the zipper tape teeth to flip.

[0007] As a further improvement of this utility model, the flipping upper mold includes an upper mold base and an upper module. The upper flipping groove is opened on the lower end surface of the upper module. The upper mold base is provided with a lifting groove. A lifting bar is fixed to the upper end of the upper module.

When the upper limit rod abuts against the abutment bolts on the side wall of the U-shaped plate, the lowering position of the lifting bar is restricted. When the lower limit rod abuts against the abutment bolts on the side wall of the U-shaped plate, the rising position of the lifting bar is restricted.

[0008] As a further improvement of this utility model, a buffer is fixed at the upper end of the opening of the lifting groove. The buffer is fixedly installed on the opening of the lifting groove by a corner plate with the buffer head facing downward. A U-shaped groove is opened on the lower side of the corner plate for the upper limit rod to slide into.

[0009] As a further improvement of this utility model, the upper flip groove is a long strip structure with a semi-circular cross-section. One end of the upper flip groove extends to the side of the upper module to form a semi-circular opening for the zipper tape to enter, and the other end extends to the lower end face of the upper module, so that the two ends of the upper flip groove are inclined to transition.

[0011] As a further improvement of this utility model, the lower tilting groove has a U-shaped structure, and the inner sidewall of the lower tilting groove is provided with a tilting step. The inner sidewall above the tilting step surface serves as a guide edge. The end of the guide edge facing the melting stop device forms an inclined surface that tilts towards the center of the lower tilting groove. One end of the tilting step of the through-head device is provided with a climbing ramp.

[0012] As a further improvement of this utility model, the zipper head insertion device includes a zipper head vibrating plate, a zipper head track, a zipper head conveying mechanism, and a zipper head insertion mechanism.

[0020] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0021] This embodiment of a concealed zipper three-in-one machine includes a zipper threading device and a stacking and flipping device. After the zipper tape is threaded through the threading device, it is fed into the stacking and flipping device for zipper tooth flipping. The stacking and flipping device includes an upper flipping mold 81 and a lower flipping mold 82. The lower end of the upper flipping mold 81 has an upper flipping groove 83, and the upper end of the lower flipping mold 82 has a lower flipping groove 84. The upper flipping groove 83 and the lower flipping groove 84 are arranged opposite to each other to form a flipping channel that drives the zipper tape teeth to flip. In the process of processing nylon concealed zippers, the tape is first fed, then the zipper tape is cut, and after the cutting is completed, it is fed into the external threading device for threading. After the threading is completed, the zipper tape is stacked and flipped, and after the flipping is completed, it is stopped by an external melting and stopping device. In this way, the zipper teeth can be effectively hidden after the zipper tape is zipped up, thereby realizing the processing of nylon concealed zippers.

[0022] As one specific implementation method of the improvement, refer to Figure 1 The zipper rollover device used in this embodiment includes an upper rollover mold 81 and a lower rollover mold 82. The lower end of the upper rollover mold 81 is provided with an upper rollover groove 83, and the upper end of the lower rollover mold 82 is provided with a lower rollover groove 84. The upper rollover groove 83 and the lower rollover groove 84 are arranged opposite to each other to form a rollover channel that drives the zipper teeth to roll over. In this way, by forming a rollover channel with the upper rollover groove 83 and the lower rollover groove 84, the zipper teeth can be rolled over easily and quickly when the zipper passes through.

[0023] As one specific implementation method of the improvement, refer to Figure 2 As shown, this embodiment provides the following flipping upper mold 81 structure, which includes an upper mold base 811 and an upper module 812. The upper flipping groove 83 is formed on the lower end face of the upper module 812. The upper mold base 811 has a lifting groove 813. A lifting bar 814 is fixed to the upper end of the upper module 812. The lifting bar 814 is slidably installed in the lifting groove 813. An upper limit rod 815 and a lower limit rod 816, which are distributed vertically, are fixed on the side of the lifting bar 814 facing away from the bottom of the groove 813. A U-shaped... The U-shaped plate has abutment bolts fixed on both side walls. The U-shaped plate is located between the upper limit rod 815 and the lower limit rod 816. When the upper limit rod 815 abuts against the abutment bolts on the side wall of the U-shaped plate, the lowering position of the lifting bar 814 is restricted. When the lower limit rod 816 abuts against the abutment bolts on the side wall of the U-shaped plate, the rising position of the lifting bar 814 is restricted. With the above-described structure, the upper flipping groove 83 can have a certain displacement space, avoiding the situation where the lower end of the upper flipping mold 81 and the upper end of the lower flipping mold 82 collide and cause damage when the zipper belt passes through initially.

[0024] Furthermore, to further enhance the buffering effect between the upper flipping mold 81 and the lower flipping mold 82, a buffer 817 is fixed near the upper end of the opening of the lifting groove 813. The buffer 817 is fixedly installed on the opening of the lifting groove 813 by a corner plate with the buffer head facing downward. A U-shaped groove is opened on the lower side of the corner plate for the upper limit rod 815 to slide into. The buffer 817 can effectively enhance the buffering effect on the upper limit rod 815 and further protect the structure of the upper module 812. The U-shaped groove is used to provide the sliding of the upper limit rod 815 during the buffering process, while limiting the left and right positions of the upper limit rod 815.

[0025] Furthermore, the upper flip groove 83 structure adopted in this embodiment is as follows: the upper flip groove 83 is a long strip structure with a semi-circular cross-section. One end of the upper flip groove 83 extends to the side of the upper module 812 to form a semi-circular opening for the zipper tape to enter, and the other end extends to the lower end face of the upper module 812, so that the two ends of the upper flip groove 83 are inclined to transition. Thus, the flipping of the zipper tape teeth can be achieved by using the inclined transition groove bottom in the upper flip groove 83, without the need for additional robotic arms or other mechanisms to drive the teeth to flip.

[0026] Furthermore, refer to Figure 3 As shown, this embodiment provides the following structure for a flipping lower mold 82, which includes a lower mold base 821 and a lower module 822. A base plate is fixed to the lower end of the lower mold base 821, and a lifting cylinder 824 is provided on the base plate. A lifting channel 825 is provided on the lower mold base 821, and the lower module 822 is slidably disposed in the lifting channel 825. A lower flipping groove 84 is provided at the upper end of the lower module 822, and the lower end of the lower module 822 is connected to the push rod of the lifting cylinder 824, thereby enabling the construction of a self-lifting lower module 822 structure.

[0027] Furthermore, the lower tilting groove 84 in this embodiment adopts the following structure: the lower tilting groove 84 has a U-shaped structure, and a tilting step 841 is provided on the inner sidewall of the lower tilting groove 84. The inner sidewall above the step surface of the tilting step 841 serves as a guide edge. The end of the guide edge facing the melting stop device 6 forms an inclined surface that tilts towards the center of the lower tilting groove 84. A climbing ramp 842 is provided at one end of the tilting step 841 of the through-head device 5. With the above structure, when the upper tilting mold 81 and the lower tilting mold 82 are assembled, the outer side of the upper tilting groove 83 and the lower tilting groove... The outer edges of 84 abut against each other, and the zipper teeth of the zipper belt on one side after the head enter from the climbing ramp 842. When entering the top of the climbing ramp 842, it will contact the bottom of the upper flip groove 83. Then, as it continues to move forward, the circular surface and inclined surface of the bottom of the flip groove 83 will drive the zipper teeth to flip downward. Finally, it will flip to be perpendicular to the belt surface by the guide edge, and then directly enter the upper and lower molds of the upper stop device 6 to complete the upper stop operation, thereby maintaining the flipped position of the zipper teeth. Compared with the method in the prior art, this method can be effectively applied to the production of invisible zipper belts.

[0028] Furthermore, refer to Figure 4 As shown, the zipper head threading device 5 in this embodiment includes a zipper head vibrating plate 51, a zipper head track 52, a zipper head conveying mechanism 53, and a threading mechanism 54. The threading mechanism 54 is located between the conveyor belt device 3 and the sealing device 6. After receiving the zipper head from the zipper head conveying mechanism 53, it threads the zipper head onto the zipper tape held by the external clamping device. Thus, the zipper head can be fed into the zipper head conveying mechanism 53 via the zipper head vibrating plate 51 through the zipper head track 52, and then the zipper head is conveyed to the threading mechanism 54 by the zipper head conveying mechanism 53, thereby realizing the zipper head threading operation. In this embodiment, the threading mechanism 54 adopts a combination of upper and lower molds. During threading, the zipper head is first placed on the upper end of the lower mold, and then the upper and lower molds are joined together. Afterwards, the zipper tape is held by the external clamping device, thus realizing the threading and separating of the zipper tape from left to right at the same time. (Refer to...) Figure 5As shown, the zipper head conveying mechanism 53 in this embodiment includes a conveying base 531, a conveying slider 532, and a conveying robot 534. The conveying base 531 is fixedly installed at the lower end of the zipper head track 52. The conveying slider 532 is slidably installed on the conveying base 531. The conveying base 531 is also provided with a receiving seat 535. The conveying robot 534 is installed on the conveying slider 532 and is driven by the conveying slider 532 to slide to the receiving seat 535 or to the zipper head insertion mechanism 54. The receiving seat 535 is located at... The output end of the zipper head track 52 receives the zipper head sent out by the zipper head track 52, which is then picked up by the conveying robot 534 and conveyed to the threading mechanism 54. In this way, the zipper head can be sent out from the zipper head vibrating plate 51 and then input into the threading mechanism 54 simply and quickly. In addition, the conveying robot 534 is mounted on the conveying base 531 by an active telescopic rod (not shown in the figure). The corresponding telescopic rod can be a cylinder or a lead screw, which can drive the conveying robot 534 to slide to the receiving seat 535 or to the threading mechanism 54.

[0029] In summary, the zipper threading device of this utility model's three-in-one invisible zipper machine employs a method where, after the threading device completes the threading process, the chain teeth are flipped using a stacking and flipping device, and then the upper stop device is used to perform upper stop processing, thereby positioning the flipped chain teeth and effectively achieving automated processing of invisible zippers.
